WARNING
Turn off the power supply and implement wiring correctly.
Not doing so may result in a serious injury due to an electric shock.
Wiring work must be carried out only by qualified personnel.
Not doing so may result in a serious injury due to an electric shock.
Do not change wiring and slide switches, put on or take off Operator and optional devices, replace
cooling fans while the input power is being supplied. Doing so may result in a serious injury due to
an electric shock.
Be sure to ground the unit.
Not doing so may result in a serious injury due to an electric shock or fire.
(200-V class: type-D grounding, 400-V class: type-C grounding)
CAUTION
Do not connect resistors to the terminals (+1, P/+2, N/–) directly. Doing so might result in a
small-scale fire, heat generation, or damage to the unit.
Install a stop motion device to ensure safety.
Not doing so might result in a minor injury.
* A holding brake is not a stop motion device designed to ensure safety.
Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking
resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might
result in a moderate burn due to the heat generated in the braking resistor/regenerative braking
unit.
Configure a sequence that enables the inverter power to turn off when unusual over eating is
detected in the braking resistor/regenerative braking unit.
The inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or
other property. Place covers on the openings or take other precautions to make sure that no metal
objects such as cutting bits or lead wire scraps go inside when installing and wiring.
